Sliding foot assembly and movable mold plate supporting structure using same

Abstract

The invention discloses a sliding foot assembly. The sliding foot assembly comprises sliding foot bodies, wherein each sliding foot body is provided with a first supporting end face and a second supporting end face perpendicular to each other. The sliding foot bodies are provided with elastic supporting assemblies which make contact with supported pieces and are used for supporting the supported pieces directly. One end of each elastic supporting assembly protrudes out of the surface of the corresponding second supporting end face, and the other end of each elastic supporting assembly is fixedly connected with the corresponding sliding foot assembly. The invention further discloses a movable mold plate supporting structure using the sliding foot assembly. Due to the arrangement of the elastic supporting assemblies, the mold locking deformation force transmitted to linear guide rails is greatly lowered, an ultra-large type machine can also be designed to be in linear guide rail guiding supporting, and the ultra-large type machine can achieve high-speed, high-efficiency and stable control production.

technical field [0001] The invention relates to the technical field of pressure forming equipment, in particular to a movement support structure of a clamping mechanism of an injection molding machine and a die-casting molding machine, in particular to a sliding foot assembly and a moving template support structure using the same. Background technique [0002] At present, the clamping mechanism of injection molding machine and die-casting molding machine mainly uses sliding fit between the movable platen and the frame when moving the mold, and uses pull rods to slide and fit guide supports. Multiple sliding fit guide supports will produce various unstable frictional resistances. It leads to unstable speed of mold moving process, high frictional resistance, slow mold moving acceleration, long mold moving cycle and low machine production efficiency. It is currently more advanced technology to use linear guide rail rolling guide support for moving template and frame. [0003] D...

Problems solved by technology

[0002] At present, the clamping mechanism of injection molding machine and die-casting molding machine mainly uses sliding fit between the movable platen and the frame when moving the mold, and uses pull rods to slide and fit guide supports. Multiple sliding fit guide supports will produce various unstable frictional resistances. The speed of the mold moving process is unstable, the frictional resistance is large, and the acceleration of the mold moving is slow, resulting in a long mold moving cycle and low machine production efficiency. The moving template and the frame are supported by linear guide rails, which is a more advanced technology at present.

[0003] During the mold locking process, the clamping force will act on the movable template to cause a slight deformation of the movable template, and the deformation caused by the deformation will act on the supporting element, that is, the mold clamping deformation force will be transmitted to the rolling elements of the linear guide rail to cause If the rolling elements of the linear guide rail fail, the higher the bearing capacity of the linear guide rail, the more expensive it will be; the greater the clamping force, the more obvious the clamping deformation, and the higher the requirements for the anti-deformation ability of the linear guide rail. For machines with a mold tonnage of 900 tons, machines with a larger mold clamping tonnage can only use sliding fit because they cannot provide linear guide rails with ultra-high bearing capacity
